“…This behavior could be seen through the analysis of the infrared spectra previous and after adsorption of the studied pollutants (Figure ), which showed that signals at 3332, 1724, 1480, and 1128 cm –1 changed their position or transmittance intensity increased after the adsorption of parabens. This is in good agreement with previous findings. − Significantly, further experimental studies are needed to establish the adsorption mechanisms.…”

Emerging contaminants are chemical products that are found in low concentrations, are not regulated by environmental norms, and cause health effects. Among this group of contaminants are parabens, a family of p-hydroxybenzoic acid esters used as preservatives in cosmetics, pharmaceuticals, and food products. Recent research describes parabens as endocrine disruptors that can cause health alterations. Some of the best alternatives for pollutant removal include the adsorption process, which can use materials that are inexpensive, abundant, and susceptible to modifications. In this sense, cellulose can be an option for obtaining materials that can be used in the removal of contaminants. This research investigates the synthesis of benzoic cellulose (MCB) and magnetic cellulose (MCM) as well as its use as an adsorbent for the removal of methylparaben (MP) and butylparaben (BP) from water. Likewise, physicochemical characterization, including Fourier transform infrared (FTIR), scanning electronic microscopy (SEM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), and thermogravimetric analysis (TGA), for both cellulose materials was carried out. Moreover, pseudo-first-order, pseudo-second-order, Elovich, Weber, Morris, and Boyd models were used to investigate the adsorption kinetics. As a result, the pseudo-second-order model was favorable for both modified cellulose and the two parabens assayed. Finally, Freundlich, Langmuir, and Sips adsorption isotherm models were investigated; the Langmuir model was the best for the adsorption isotherm data. The adsorption of methylparaben and butylparaben was in the following order: MCM > MCB. The maximum adsorption capacity of MP and BP for MCM was 9.58 and 12.03 mg g −1 , respectively. For instance, the results showed that the modified cellulose adsorbed the parabens physically, which could involve electrostatic attraction, hydrogen bonding, π−π bonding, and hydrophobic interactions.

“…Carbon materials obtained as a result of pistachio nutshells pyrolysis, physical activation with the use of CO 2 or steam and chemical activation with the use of ZnCl 2 , K 2 CO 3 , KOH, NaOH, NH 4 NO 3 , H 2 SO 4 or HCl have turned out to be effective adsorbents of various types of organic and inorganic pollutants. Activated carbons obtained in this way can be successfully used for the removal of NO 2 and H 2 S [31], SO 2 [32], VOCs [33], organic dyes [34], phenolic compounds [35], parabens [36], pharmaceuticals [37], cyanide [38], heavy metal ions [39], transition metal ions [40], etc. In addition, they can be used as promising electrode material for electrochemical capacitors [41] and catalysts or catalyst supports [42].…”

Carbon Adsorbents Obtained from Pistachio Nut Shells Used as Potential Ingredients of Drinking Water Filters

Water resources are increasingly degraded due to the discharge of waste generated in municipal, industrial and agricultural areas. Therefore, the search for new materials enabling the effective treatment of drinking water and sewage is currently of great interest. This paper deals with the adsorption of organic and inorganic pollutants on the surface of carbonaceous adsorbents prepared by thermochemical conversion of common pistachio nut shells. The influence of the direct physical activation with CO2 and chemical activation with H3PO4 on parameters, such as elemental composition, textural parameters, acidic–basic character of the surface as well as electrokinetic properties of the prepared carbonaceous materials was checked. The suitability of the activated biocarbons prepared as the adsorbents of iodine, methylene blue and poly(acrylic acid) from the aqueous solutions was estimated. The sample obtained via chemical activation of the precursor turned out to be much more effective in terms of all the tested pollutants adsorption. Its maximum sorption capacity toward iodine was 1059 mg/g, whereas in relation to methylene blue and poly(acrylic acid) 183.1 mg/g and 207.9 mg/g was achieved, respectively. For both carbonaceous materials, a better fit to the experimental data was achieved with a Langmuir isotherm than a Freundlich one. It has also been shown that the efficiency of organic dye, and especially anionic polymer adsorption from aqueous solutions, is significantly affected by solution pH and temperature of the adsorbate–adsorbent system.
